Kate
Kate 26.04.12063 is KDE's code editor with project views, syntax highlighting, an integrated terminal, LSP support and plugins. This entry covers the macOS arm64 package and workspace boundaries.
What Kate is for
Kate is suited to editing code, configuration and documentation through project views, syntax highlighting, language-server integration, an integrated terminal and plugins. Builds, debugging and dependency management remain responsibilities of the language toolchain, and editor permissions should be kept separate from project trust.
Version and macOS boundary
This page covers the Kate 26.04.12063 macOS arm64 DMG. Confirm the Mac architecture, project directory permissions, language runtimes and configuration location after installation. Start with a small project that contains no production secrets.
LSP, terminal and plugins
Language servers and plugins commonly run external processes and read the workspace. The integrated terminal can execute project commands as the current user. Review launch commands, working directories and permissions before enabling an extension, and keep user settings separate from project settings.

Kate 26.04.12063 macOS installation, project and LSP guide
Verify editing, saving, terminal access and syntax highlighting in a small project first, then enable only the language servers and plugins required for the target language.
Before you start
- Confirm that the Mac uses Apple silicon and prepare the macOS arm64 DMG plus the required language runtimes.
- Use a test project without production secrets and record its directory permissions and build commands.
- List the language servers, formatters and plugins you need, then review their source, version and launch behavior.
Installation steps
- 01
Install the macOS arm64 DMG
Open the DMG and move Kate to Applications, then verify the version and review file-access or terminal permission prompts at first launch.
- 02
Open a project and set editing defaults
Select the project directory and configure indentation, encoding, line endings, saving and syntax highlighting; edit a sample file and inspect the version-control diff.
- 03
Enable one LSP and the terminal
Configure an installed language server for one language, check diagnostics and completion, then run a read-only build or test command in the terminal.
Quick start
- 01
Establish project settings
Document formatting, build and test commands, and separate user settings from project settings so local paths and credentials are not committed.
- 02
Observe LSP and plugin processes
Check each server's launch command, workspace path and resource use; disable the newest plugin first when an issue appears and keep its log.
- 03
Create a restore point
Commit or export a patch before major edits, and back up settings, the plugin list and project configuration before upgrading Kate.
Usage tips
- The integrated terminal and external tools can execute project commands, so open untrusted projects with minimum privileges.
- LSP completion and diagnostics depend on the language toolchain, compilation database and project configuration; they do not prove a build will pass.
- Workspace settings, terminal history and plugin caches may contain paths, tokens or internal addresses. Clean them before sharing.
Troubleshooting and uninstall
Why are completion and diagnostics missing?
Check the language server installation, launch command, project root and compilation database, then inspect its log with a small project before changing multiple settings.
Why does Kate slow down on a large project?
Narrow the project root, exclude build and dependency directories, reduce concurrent servers and plugins, and check disk and indexing usage.
- Save the project and editor settingsCommit or back up code, export required settings and plugin details, and remove sensitive commands from terminal history.
- Remove Kate and selected configurationQuit Kate, remove it from Applications and clear user configuration, caches and language-server settings only when they are no longer needed.
Frequently asked questions
What languages can Kate edit?
Kate can edit text, configuration and many programming languages. The available completion, diagnostics and formatting depend on the language server and toolchain installed for the project.
Does enabling an LSP run code?
A language server normally runs as an external process and may read workspace files. Review its source, path and launch command, and enable it only for projects you trust.
How should plugins be managed?
Install only necessary plugins, review permissions and update sources, and disable the newest plugin first when diagnosing a regression. Back up settings before a major upgrade.
